According to search-discovered classical Islamic scholarship, the concept of Al-Wasiyyah (the Will) is a profound and dual-faceted injunction. Primarily, as detailed by jurists like Al-Qurtubi, it refers to the legal instrument of a testamentary bequest—a recommended act of charity allowing an individual to designate up to one-third of their estate to beneficiaries who are not prescribed heirs under the fixed laws of inheritance (Mirath). This is underscored by the Prophetic tradition limiting the bequest to one-third to protect the rights of the mandatory heirs. However, exegetes like Al-Tabari highlight the term's broader linguistic meaning of a solemn command or charge. In this sense, the Quran is replete with Allah's 'Wasiyyah' to humankind, such as the sacred injunction to show kindness to parents (Quran 29:8, 31:14) or the charge to uphold justice. This synthesis, integrating the legal framework from Fiqh and the spiritual and ethical mandates from Tafsir, reveals Wasiyyah as a sacred trust that governs both the responsible transfer of wealth after death and the fulfillment of divine commandments throughout life, ensuring justice and piety are connected across generations.
